To all whom it may/concern; r v r Be it known I that I, AUGUST 7 PI'F'lELKOW, acitizen of theUnited; States,-residing at Chicago, in the c0uI1ty;, ),f (look and State of Illinois," have invented a jcertain new and useful Improvement in Looks for Box Y L ds and the like, of which thejfollowing jis' a specification. I

. to prevent accidentalopening duringtransit 'is' to provide a in use and readily unlockedwh'en adelibcondition.

out the several vlewsL- a v v The box lhas alid 2..which is hinged and at the same time permit thebox.Itob'e V readily opened at anytime withoutithe aid of the key. Myf clevice is, particularly ap} pli'cable to, metal boxes in which inflammable articles" areshipped, for example, mov ng, picture films. Thefobjec't of the invention lock of this character which, shall be of simple construction, securewhen erate attempt is made to unlock it. M

I accomplis'h my object by the construction illustrated -in the accompanying draw-j 1 ing in which- 25 V with the invention applied to it.

Figure 1 i In full lines the locking device. is shown in locked- Figure 2 is a perspective view showing thelock in position torelease th'e-hasp.

Figure 3 is a perspective view of the part which I shall term the 'arch and. which is analogous to the stapleof an ordinary hasp lock. V

Figure 4 is a perspective View .ofsthebl'ock which effects the locking action. 7 I Like numerals denote like parts through at the back; Atthe front is a'hasp llwhich' is hinged at its upper end to'the frontof the box lid; It has an aperture 6, which is elongated and accommodates an arch" ,8

rigidly secured to the front wall ofthe box in such position thatthehasp may fit-over it when lowered to the full line position shown in Figure 1. 'VVhile the shape of the arch may be varied to acertain extent, in

the form shown it has feetllO atthe ends by which it may be spot welded; soldered, riveted or otherwise According to inventim ila-t's 1 amban and the like, and. is ofitheiypew employe the consequence i's that by proper manipu; latlon'the maybe rotated sufficiently to bring lt'entirelyi 1n 'frontofthe'aperture releasedjl sa perspective view of the b0) 2; "This makes it possible for the operator secured t0 the; front o f the arch between .the'notches '12 isslighe lyf'shorterj'thanvfthe length of slotil fi and in a fpi p r i gt h s 1w; b

To, look the box thearch 8 to mid position and then rotate it toivertical position, portionsof the block entering the'notches 12 as shown inFigurev to lower th$hflSP over theblock and arch to the position shown fin Figurev 2. -When i :thls' has been: accomplished the operator rotates the block back again so that it will come crosswise'of aperture 6. As the length ofthe, blockiisgreaterthan thewidth of the aperturejit 'is evident "that the hasp will nowbe locked. The'operator may now res lease the block, that is, let it drop by gravity to} the lowerend of the i arch whereuponlit will hang 'lII-VGItlQalPOSltlOIIZaS shown "in Figure 1.' This is thefinal locked position.

-and' obviously gravity will tend: tomaintain f the block in thisposit'ion. Even. though the box be handled roughly or placed in various .1 positions'lthere islittle danger-of thejblock permitting the 'hasp to be freed. I

VVhenit is desired to unloc'k the-box the reverse operation is performed; The 0perator simply lifts the block to .approxi mately-the mid position of the archand with and in front of the aperture in "the; ha'sp. Oonsequentlyit be. seenthat the;

' the arch so that .wh'enthe hasp. is lowered to" locked positionjth archwill beap ibx'i. H l matelyfco' extensive with the aperture? 7 l jffBetween the ends of'the arch arelno tchesj l 1a tone-on nd, ne o ih h r;

It 'h&S' .1 fSlOt 16,1the11engthf of which is "slightly greater; than thejfull width; of the I 7 I ,arch". Consequently theblock 'i'sfreely slid I able,along'the" arclifbutfis permanently secured to. it. "The iiiterln'ediate portion v18 then rotates it approximate1y90 degrees tof: I

bring the plane of theblock "in *alinement,

operation of locking and unlocking is extremely simple and requires'no detached key of anykind and yet when the box is locked it will safely remain so.

Having thus described my invention what I claim as new-anddesireto secure by Letters Patent is:

l. A hasp lock having a ha s'p witha-slot arranged longitudinally and having uninterrupted parallel sides and twolocking elements, .one of which constitutes an arch projectable throughthe slot in the hasp and the other constitutes a locking block having an aperture through which the arch passes, one of said locking elements having a plurality of oppositely disposed indentations of sufficient depth to enable the locking blocktobe rotated about anaxis perpendicular to the plane of the haspto a position substantially in line with the arch to enable the locking block to occupy'either of two positions, VlZ crosswise of the slot for locking t-he hasp or lengthwise of the slot for releasing the hasp.

2. hasp lockhaV'ing an arch, a hasp apertured to fit over it, and a block whose width is greater than the width of the aperture inthe hasp and whose thickness is less than-the width of the'aperture, said block being permanently'connected to the arch and loosely mounted on it, and the arch' having indentations in the side for permitting'the block to be rotated'to a position entirely in front of the aperture for releasingthe hasp.

3. A hasp lock having a hasp with an aperture in it, an arch which in the main is approximately of 'the' same "width as the aperture," and a blockwhose width is greater than the width of the aperture, and whose thickness is less than the widthof the aperture, the block being slidable lengthwise of the arch, and'the arch having notches in the side whereby the block is also rotatable on the arch to enable it to lie wholly in the front of the aperture for releasing the hasp. V

4. The combination with a box and cover of a hasp secured to one part and anarch secured to the other, and a'block which encircles the arch and is therefore slidable on it, the width of the block being greater than the width of the aperture and the thickness of the block being less than the width of the aperture, the arch having notches for permitting thefblock to be rotated to a position'wholly'in front of the aperture, the notches beinglocated between the ends of the arch whereby when the block is at one end of the arch'ftheblock will be nonrotatable and hence hold the hasp in locked position.

In witness whereof, I havehereunto subscribed my name.

AUGUST PITTELKOW.
